DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

Broadly, an embodiment of the present invention provides a collapsible shelter assembly that is foldable from a compact configuration to an operative configuration for providing a portable yet sturdy shelter, and foldable back to the compact configuration for storage and transportation. The shelter assembly may include a floor system independently connected to a plurality of walls by pivot connecting devices, enabling the plurality of walls to be independently foldable. The floor system has an upper surface defined by periphery edges. A plurality of curbs, each with a different height than the other cubs, are perpendicularly joined along a portion of the peripheral edges, providing different wall-to-curb connection points and thus different pivot points for even identical pivot connecting devices, enabling the pancake stacking of the plurality of walls in the compact configuration.

Referring now to FIGS. 1 through 7, the present invention may include a shelter assembly 60 that may be foldable from a compact configuration to an operative configuration, as illustrated in the Figures. The shelter assembly 60 may include a floor system 12 pivotally connected to a plurality of walls 70 so that each pivotal connection to each wall of the plurality of walls 70 is independent of the other pivotal connections. One pivotal connection to each wall may include a plurality of pivot connecting devices 20, including but not limited to a hinge.

The plurality of walls 70 may include a front wall 22, a right wall 30, a back wall 34, and a left wall 38, as illustrated in FIG. 4. The floor system 12 and pivotally connected walls 22, 34, 30, 38 may be generally planar and made of generally impermeable, rigid material that that can be repeatedly bent without fracturing, such as metallic materials, various impregnated or laminated fibrous materials, various plasticized materials and the like.

The floor system 12 and pivotally connected walls 22, 34, 30, 38 may form a substantially rectangular in shape, though other geometric and non-geometric shapes may be formed so long as the floor system 12 and pivotally connected walls 22, 34, 30, 38 function in accordance with the present invention as described herein. The floor system 12 may include an upper surface 11 and an opposing downward surface. Interconnecting the upper surface 11 and the downward surface is a plurality of peripheral edges 13 defining the upper surface 11 and the downward surface. Each peripheral edge 13 may be associated with one of the pivotally connected walls 22, 34, 30, 38.

The present invention may include a plurality of elongated curbs 15: a right curb 14, a back curb 16 and a left curb 18. The plurality of elongated curbs 15 may be perpendicularly joined to the upper surface 11 along at least a portion of the peripheral edge 13 so that an outer surface of each curb 15 is flush to a portion of the peripheral edge 13. Each elongated curb 15 extends along a longitudinal axis, and each curb has at least one outer surface—the transverse surface 19—extending along a transverse axis, wherein the transverse surface 19 would be associated with and defined by the ‘height’ of the curb 15 just as the ‘12’ in ‘2×12’ defines the ‘height’ of a wood structural member. The transverse surface 19 is the surface flush with a portion of peripheral edge 13. The curbs 14, 16, 18 may be dimensioned so that each transverse surface 19 extends a different distance/height compared to the other curbs, thereby each extends above the upper surface 11 by a different distance, as illustrated in FIG. 4.

The pivot point of each pivot connecting device 20 may be generally defined by the (height of) transverse surfaces 19 and/or an uppermost point of each curb's 14, 16, 18, or, in the case of the wall (in the illustrated embodiments, the front wall 22) that has no curb, the upper surface of the floor system 12. As a result of such staggered wall-to-curb/peripheral edge connection points and thus pivot points, the pivotally connected walls 22, 34, 30, 38 are foldable so that each pivotally connected wall 22, 34, 30, 38 pancake stacks on or underneath an adjacent wall when positioned in the compact configuration, as illustrated in FIG. 5, even if using identical pivot connecting devices 20 throughout to save manufacturing costs.

The present invention may include a roof 42 having a plurality of attached corrugated coverings 44, 46, 48, 50, 52. The roof 42 may be removably connected to an upper portion of at least one of the walls 22, 34, 30, 38 by standard fastening means.

In certain embodiments, the front wall 22 may form a door cutout. A door 24 with a door knob 56 may be operatively attached along a periphery of the door cutout with door hinges 58. Any one of the walls 22, 34, 30, 38 may form a window cutout. In certain embodiments, a window 54 may be operatively attached along a periphery of the window cutout. In certain embodiments, the present invention may include corrugated coverings 26, 32, 36, 40, 28 for connecting to the walls 22, 34, 30, 38 and the door 24.

In certain embodiments, the present invention may include a floor covering 10 dimensioned and adapted to cover the upper surface of the floor system 12.

A method of using the present invention may include the following. The shelter assembly 60 disclosed above may be provided. With the downward surface supported by a supporting surface, such as the ground, the user may unfold the pivotally connected walls 22, 34, 30, 38 from the compact configuration to the operative configuration. Then the user may removably attached the roof 42 to at least one of the walls 22, 34, 30, 38 so as to form a durable, temporary shelter that can be used as an ice shanty, shed, safe harbor or the like for the long term, before being folded into its compact configuration for easy transport, storage, and subsequent reuse. As illustrated in FIGS. 5 through 7, the pivotally connected walls 22, 34, 30, 38 can be folded onto the floor system 12 in the compact or stacked configuration.

It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the present invention.
